All you have to do is make up a relationship between the name and the physical characteristics of the person's name you are trying to remember.

For example, if you were trying to remember a person by the name of Tom, you might associate their name with the person you went to prom with who was also named Tom. In this instance, you are making the connection between Tom and prom (rhyming) and between someone you previously knew from high school.

If you want to remember the name Sally, you might imagine them in a ballet. This association will help you remember their name because of the visual imagery and the connection between the "closely related" words that almost rhyme: Sally and ballet.

By making connections, you are instantly more likely to remember their name the next time you see them.
